Actually, based on what I read in some posts and on the wiki pages, I think this is technically possible - just not easy to do it at the end user level right now. Specifically, an authorized tuner (with access to the create new CustomROM function inside BM3) would need to create a "new" CustomROM multimap file, then basically "cut & paste" the tune files of your choice into the map slots - like the example above (with the accompanying costs to do it as described in another post).

If this is not how it works, then I believe the "catch" is that all tune maps in the map slots need to be similar tune files that share some base line elements. Remember, the tune "file" inside the DME contains over 4800 different maps/parameters that control the engine. Only a subset of those 4800 maps/parameters are actually manipulated by tuners when creating different tune files with different power levels and/or fuel type requirements. So, for example, the Stage 1 OTS map and a Stage 2 OTS map and stock map may not share enough base line elements to be bundled together in a CustomROM multimap. So this could be a practical limitation of the DME that can't be overcome - at least not yet.

I am not a professional tuner by any stretch of the imagination. What I described in the second paragraph above seems like a technically plausible reason why you can't bundle just any map of your choice. However, I hope that I am wrong as I would like to be able to bundle tune files if my choice, similar to the ones above.
