I use a modified version of an old combine.mac that
@ChatWithThisName modify and share around - there are a few versions floating around - it used to be in the VV compile, but might not be any longer?
this one is set to delete collapsed toolkits and crab crackers (cwtn was doing tinkering iirc)
you select your recipe in your tradeskill window and
/mac combine
should probably adjust it at some point to check for bagspace
if combine.mac isn't in your macro folder, you can just download this and toss in your release->macros folder and then do the /mac combine as mentioned earlier
