you can pass multiple strings into the constructor that makes a ulx command to have multiple chat commands tie to one

in chat.lua
local psay = ulx.command( CATEGORY_NAME, "ulx psay", ulx.psay, {"!p", "!pm"}, true )

now that I have provided a solution you can expect to wait 6-12 months for it to be implemented

Shit bro. I use SAM and I don't even have the ability to do that. I just gave up and ended up adding a clone command.
