Allow for encumbrance limit multipliers

Feature Summary

Right now, the only way to change how encumbrance works is by altering the encumbrance die with an active effect. This doesn't work for something like the Mule cyberware, which multiplies the load you can carry with Strength times 8. It doesn't matter how high I set the encumbrance die, the maximum load always seems to be 100, and there's no way to tweak this that I've found.

Simply put, I want the ability to change the maximum encumbrance in sheet tweaks.

Priority/Importance

Relatively important, since it seems impossible to do otherwise. And it seems like a fairly simple tweak.
