Pak Utility Mod Question

I apologize if this has been asked somewhere else, but I cannot seem to find an answer. Can anyone tell me if it is possible to change the keybind for flying down in Pak Utility Mod? For instance, use the same key as crouch to go down?

I am using Pak Utility Mod for flight and also using the Smart Mod for extending foundations, and unfortunately, they both use the Alt key (trying to extend foundations while flying is nearly impossible because Alt makes you fly down).

Thanks in advance for any help!

sadly no. unless it has a config file no
