Edit with clip form

I've created a clip definition file for an obscure script language I use. I can successfully press Ctrl-Space, select an instruction, complete the parameters form, and insert the instruction by clicking the Ok button on the form. I'd like to know if there's a way to somehow select an existing instruction in the current document and have PSPad reload the parameters into the form for editing and then replace the current instruction and parameters once the form is closed with the Ok button. If this functionality doesn't exist already it would be a nice addition in a future version.

No, there isn't back editing. Code parsing can be a hard for general purposes, some properties can be lost, especially when clip has been edited later manually.
