update source model default

In the model settings -> Source Models you are able to edit a mapping and change the source to e.g. the production model rather then the development model.

For some of our models we have recreated multiple development models (copy of production) this resulted that as source model there are a lot of non existing models listed:

Model A

Model A~1

Model A~2

Model A~3

Model A~4

All of those models are then 'Mapped To' the correct 'Model A'.

It would be nice if you could update the default Source model which results that multiple original source models are merged into one single one. This will make to overview much leaner and lower the risk that a remapping get missed.
