Virtual File Names for outbound data

one of my trading partners has some (historical from OFTP1 times) strict requirements how the virtual file name should look like and be composed, starting with an ENG (thats the easy part, succeeded in this in the partner parameters), follwed by the timestamp (done by the OFTP2 SW) and then a sender ID (ako of name string) - I suppose this is possible using the macro replacements for 'Send' and 'Receipt' under 'Events' for the partner ?

thanks and regards - Ralf
