You could do something close with a little leg work, but no, you can't merge repeat region cells. There are a couple of ways to do this:
1. Use comment cells, add a column to the table that is included in the repeat region, but is reporting no parameters, then from the repeat region menu manager, select "Comments" and pick the first cell in that blank column. You can then right click / properties on each cell in that column and manually add an index to be whatever you want.
2. You can create a relation in the repeat region so you can set the index to whatever you want, including having multiple objects with the same index.
From the repeat region menu manager, select Relations and click on the repeat region. Then start a series of if / else statements like:
if asm_mbr_part_no == "12345" [the "asm_mbr_" part is required, then add the parameter name, ie "part_no]
my_index = "1"
else
if asm_mbr_part_no == "12346"
my_index = "1"
else
...
endif
endif [you need one endif for each if]
Then edit the repeat region, so instead of showing rpt.index, change it to rpt.rel.my_index. It's not an elegant solution, doing this for large assemblies would be a pain, and if you change the assembly, you must change the relation also.
Either way, you can't merge the cells, but you can give more than one item the same index number.
Hope this helps,
