[Scid-users] merge a game

[<so...@fr...>]

Dear scidlisters,
I have an issue which has recently come up dealing with the merge function. 

I am using Scid 4.3.

Is it possible to merge a game at a choosen move? 
Scid does not always recognize that two games have reached the same position with different move orders. Thus, the merge is not properly made.

For instance, the following two games have reached the same position at move 10 with a complete different move order.

How to force the second game to merge at move 10 in the first game? And not at move 2!
Can anyone please help me out?
Thanks!
