https://wiki.logos.com/Lectionary_and_Harmony_Support gives useful information on the use of dynamic text in PBs. In particular it covers the res parameter as follows.
Res
Optional – Forces dtext to be pulled from a specific resource e.g. Authorized Version:
{{dtext ref= 1 Co 4:6 | res=LLS:1.0.3}}
I have tried to ascertain suitable parameters for other bible versions without success.
Does anyone have a list??
