Problem : dynamic function name in MQ4

I have the following example:

if ( expertname == "MFI" && version == "1.0.0.4" ) {
      //Print(" mfi4_0_0_0_0 is entering",expertname, version);
      mfi1_0_0_4(magicnr, istf);
      return;
   }

With this method I have to create for each new version each new if-block. Are there some simple way to create "dynamic function name" so that when I create a new version, I do not need create a new if-block?
