Copy a range of cues and merge them all into a unique one

I need to copy 2 cues like 1+3 and merge it in a new cue 6,the only way I am getting this to work is using the edit cue 1 edit cue 3 record 6 isn’t there anoter way with copy but merge in one new cue?
why can’t it be something like copy cue 1 +2 @6 enter" pop up “do you want to MERGE ?” .
Thank you!

+1

I believe this is more complicated than first glance. See my random thoughts/opinions on this at Copying different cues into a new single cue
