@JMD - I just seen over here in the Stasher thread: [MOD]Stasher v11 fo 1.1.4.1(GDx2) Include source data (links to post 84 of the thread).
…if you follow the conversation from that point on with them working out what to do etc it seems some headway (I think?) was made getting Stasher updated. Seemed like it might be relevant for you so hopefully there is something useful there for you to use.
Edit: and actually, looking at the top of the thread - [MOD]Stasher v11 fo 1.1.4.1(GDx2) Include source data - I think that they might have managed to get Stasher fully updated to 1.1.4.1.
