Can parts be grouped in the tech tree?

[Wyzard]

Is it possible to group several parts together as a single part icon in the tech tree, so that paying a single entryCost will unlock all the parts in the group?  I think I've seen that done before, but I can't find any examples or documentation for it, so I might just be imagining things.

No

Hmm, OK.  I can believe that, but I could swear I've seen a part description on the tech-tree screen that said "5 more parts in this group", or something like that.  A picture and description of one part, with a note that there are others associated with it.  But like I said, maybe I'm just imagining things.

Edit: Turns out I was thinking of the "2 subtypes" line shown in the description for parts that use B9PartSwitch.  That's different variants of a single part, not different parts entirely.  Mystery solved.

This actually is possible now in 1.2. There is a line that can be added to the part config file called identicalPart. You can set that as a comma separated field and every part that is grouped in there will unlock with the part where you placed the config. 

identicalPart = Part1, part2, part3, etc

Oh, that's useful, thanks.  It doesn't actually group the parts together under a single icon in the tech tree (which is OK), but it makes it so that paying the entryCost for one part will unlock the others too.  Looks like it needs to be set on all the parts in the group, not just one of them (otherwise the "purchase all" price may be wrong, and purchasing a part that doesn't have the attribute won't unlock its counterparts).

The attribute is actually named "identicalParts", btw, not "identicalPart".
