Savings texture to png and then making asset bundle

Situation:

In my editor script, i am creating a texture from scratch and then saving it as a png.

Right after that, I try to save it into an asset bundle.

Problem: Unity hasn't imported the texture yet, after saving it, into unity. Which means I can't save it to the asset bundle. The only way for me to do this, is first to create the texture and than wait for a bit for unity to import it. After that, I can save my assetbundle.

This is NOT a valid option for me, I need to save it immediately as an asset bundle, so is there a function in unity editor to import the texture manually right after saving it?
