It does not matter if it requires additional work or layers to achieve it, I would appreciate it if anyone can let me know if there is a way. Perhaps a third party plug-in would also help if there is one.
Instead of a plug-in you can try a plug-out. Blending mode ADD is available in some other vector drawing programs. Affinity Designer is one of them. Versions 1.x were a light-year behind the capabilities of Illustrator, but versions since 2.0 have spurted much closer. Get the free trial, watch tutorials and try.
Illustrator has practically no tools for drawing nor editing bitmaps. Affinity Designer supports much better those who do not eschew mixing bitmaps and vector shapes.
