The only way I know is to set it up with Macaroon and copy the variables over.
Should at least work if you only use macro buttons (macaroon feature) but might work for normal buttons in some cases too.

Macro buttons are pretty sweet anyway since their macros can be up to 1023 characters or so, I need to use those more...
Macro buttons are stored locally though, so be sure to back them up somewhere in case your computer takes a dive someday.
