My idea is as follows:

1. provide a parameter (P_subrepo) for subreport selection in the main report.

2. place one subreport component in the main report.

3. Set '$P{P_subrepo}' to the expression of the subreport component.

The user can select and display the subreport in the input control on the main report.
