Hmmm, tough one. First, of course, either clean your sensor or send it off to be done as this will get rapidly tedious and worse over time – eventually making your camera unusable.
First off, FIND all your spots. This is a pretty good article: https://photographylife.com/how-to-spot-dust-on-your-dslr-sensor
2 ways:
1) create the spot fix as a development setting in camera raw (using ONLY the spot fixes), load your pix directly in camera raw and then apply the pre-made spot fix (use a sample image from the above article to try creating one). Remove spots that aren’t needed. Voila!
2) Make an action in Photoshop – basically, open a new image, start recording, place your spot heals, stop recording. When you open a new image, just apply the action. This will require every image to be the same size, of course (for example, my pix out of my camera are 5184 x 3448 so any corrections for photos would have to be that exact size).
I think the better way is the development setting in Camera Raw/Bridge.
