Custom Abilities & action costs

[Thrawn82]

I was working on adding some scripts for a campaign I am running and I ended up needed to add some custom characters from Extinction Curse.

I seem to recall when I was making custom monsters earlier, when you created a custom ability it was possible to assign it an action cost to use. I don't see this option anymore, was it removed or moved elsewhere? is there another method of marking a custom ability as having actions to use in the actions portion of the sheet?

thank you
