Importing yahoo data via Amiquote overwrites my existing Aux1 + Aux2 fields

On a weekly basis I will run amiquote (yahoo) to update/ refresh my database which contains some pre-calculated Aux 1 values. This would always make the Aux 1 fields to 0.

Is there any way to prevent that? There is a similar topic on this, but it seems like it does not solve the problem.

NOTE: the objective is not to update the Aux 1 after each time I use the amiquote yahoo update.

Thanks in advance

You need to use HYBRID mode as explained in the Knowledge Base:
