P: Save and recall multiple Watermarks

I grew up with lightroom classic like most and having the ablity to watermark and save it for future comes real handy only issue now because social media e.g Instgram is now cropping off images we need the logo slightly higher etc but with lightroom classic you are limited to 10 after clicking one of the edges which is not high enough. You can click center but it locks in place, so you got a gap between middle and 10 from  the corner anchor (white theme)

While editing on my tablet / lightroom (black theme) some reason you can move between / anywhere without no issues..... but the only downside is that you can not save the watermark / preset the logo for future use and go back and forth between different logos

Or am i missing somthing please advize
