vim-latex: Automatically recognize custom commands

I switched to vim-latex and have the following issue: I frequently define new convenient commands for easier editing via \newcommand. My own commands usually take 2 or more parameters.

So let's for now assume I creat开发者_StackOverflow社区ed a command mycommand that takes 3 parameters.

Is there a way to tell vim-latex to automatically recognize my custom commands, so that I can simply type mycommand and press <F7> (or anything equivalent) and vim automatically converts this to \mycommand{<++>}{<++>}{<++>}<++>?

Note: I know about Tex_Com_name, but since I create new commands that often, I don't want to do this all the time.

Since this seems to be a nonexistent feature in vim, I've created it myself. I didn't do in-depth tests, but it seems to work quite well so far.
