Select specific units from different short courses for single statement of attainment

We do not have any full quals on scope, so all units are created as standalone units of competency (recognised by aXcelerate as the same qualification)

Our clients will often undertake a number of short courses over a period of time, which collectively will make up a skill set (this skill set is not recognised).

We could use the Multiple Class Enrolment feature to amalgamate these units to the one certificate, however it does not allow us to select specific units, thus showing all units back to the year dot.

I want to be able to, using something like the Multiple Class Enrolment, to select those specific units I want to show on the one certificate.
