You or your developer will need to do some jumping around hoops in order to make this happen.
Off the top of my head. Alexandre suggestion is a good place to start: you'll need to work with structure CEKKO inside FM ME_REL_STRATEGIE_EKKO. There should be an point inside that FM where you can add an customer enhancement to modify the contents of CEKKO so that the flags that inform the rest of the program to redetermine the release strategy arent set.
