[MusoBob]

The whole idea of this exercise is to find out what chords you need not what chords you don't need or know, any you don't need can easily be deleted from your hard drive or SSD but how do you add a chord that's not there ? "MusoBob that guitar you recorded sounds great I can use that in my next song but I use this "&%#*" chord in my songs a lot but I can't find it, can you re-record it for me with that guitar"
If you have to go and buy loops they usually just have a few chords, you can't transpose a m into a m7.
