Run a "different" subreport depending on the variable

[Kot_Ciapucha]

hello there,
I have Main report which contain variable, which has returns value.
Main variable:
- P12346
- R123456
- D123456789
I get the first character from a string (it is my variable):
- P
- R
- D
Is possible run different sub-reports who depends from variable?
- P - Subreports "A" with parameters
- R - Subreports "B" with parameters
- D - no subreport
