Request Feature: Maximum or Sum integrator for tracking asteroid motion against stars

I am in the middle of a couple of projects tracking the asteroids Ceres and Pallas. I need to stack the images without integrating out the moving object. To do this I need an integration option that sums or maximises the FITS data, rather than averaging it. This should be a quick and easy addition. You would just need to add a new integration option with slightly different maths.

Deep Sky Stacker has a maximum integration option for this type of thing.

What would be really cool (but more complicated), is to be able perform two integrations and blend them. One integration of the background stars using median/average stacking, and one integration of the moving object using maximum or sum stacking. You could then use a winsor/sigma rejection map (or something similar), as a blending mask to combine the two integrations.

(N.B. What I am wanting to do is different from comet stacking. I want to see the moving object in its different positions over time against the background star field.)

Thanks a lot for this suggestion! I think this is definitely on the radar of Mabula as I know comet stacking is as well. Unfortunately it is something a bit more "down the road".
