multiple watermark versions

Hello

I am testing this plugin, and am very excited that it seems to be working well, and is well thought of.

My one question is, if it is correct that I can only create one text based watermark? I understand by the documentation that only one watermark can be applied on each file but I wanted to create different watermarks, to apply on certain files, but when I go to create new watermark, the text watermark option is greyed out (I assume this is because I already have a text watermark?)

I see multiple function for this, for example different opacities, to apply on dark or light images, and maybe also different font colors, to use white font on dark images, or dark font for light images.
