Is it possible to achieve this functionality: continuous merging?

[sololll]

There are tow forms of continuous merging:

1.Manual
After merging A and B to get "AB" without saving, you can continue merging C to obtain "ABC". Furthermore, you can continue merging D, E, F, and so on.

2.Automatic
Pre-configure the merging checkpoint order, Calculation Mode, Alpha, and other parameters, and activate the automatic function to seamlessly execute the predefined merging plan.

I'm unsure if the current version can achieve the mentioned functionality. If it can, that would be incredibly convenient.
