You can select one of the pedal controllers for each of the PEDAL sockets: Wah, Volume, Pitch, Morphing.
Yes, you could morph a volume like Rig Volume, but since you aim for four expression pedals anyhow, that is not meaningful. Use your dedicated Volume Pedal instead with Rig-specific parameters like Volume Pedal Location and Volume Pedal Range. This way Morphing is free for other tasks.
It makes no sense to configure two Morph Pedals. You can only have one set of continuous parameters to be morphed per Rig. So these two pedals would be in constant competition.

That I didn't know , it means I cannot have a morph delay pedal + morph reverb pedal at the same time on a given rig if I understand well ?
Many thx for your expertise
Morphing and Morph Pedal are unique, while the parameters can vary by Rig. So you could morph Reverb Mix in one Rig and Delay Mix in another. Or both simultaneously within the same Rig. But not independently within the same Rig.
Am I also right in thinking you can have pedals assigned differently per rig, these are global settings?
I wondered because I have 3 pedals, 1 I use for volume, 1 for Wah and 1 for pitch ( mainly whammy) which I use rarely. Id love to cut down my board to 2 pedals by trading volume and pitch, not sure this works even with the pitch to volume link??/
There is no Pitch to Volume link. You could only link both Pitch Pedal and Volume Pedal to your Wah Pedal.
I would just link the Pitch Pedal to the Wah Pedal and stick to a dedicated Volume Pedal. For Wah and Pitch Pedal effects the heel position is the usual starting position, while for a normal Volume Pedal the toe position is the starting position, which requires conscious handling.
You could also establish a Moprh Pedal and link Wah Pedal plus Pitch Pedal to that. Than you could control Wah effects, opportunistically Pitch EPdal effects and once in a while perform Morphs.
You just need to be aware that the controllers for Morph Pedal and Wah Pedal and Pitch Pedal - when linked - move simultaneously. If you want to just trigger a whammy effect, you need to make sure, that there is no Morph and no Wah effect or the Wah effect is inactive in the Rig presently loaded.
If you would like separate control within the same rig, you should be able to accomplish this with a separate midi controller. Perhaps like a Boss EV-1-WL expression pedal.

I thought so, I tend to use switch morph rather than pedal control and so prob doesn't work for that reason. A new feature request methinks
