Lightroom export resize image and add watermark relative to new size

[Lichtjager]

I came across this strange thing: I exported my pictures in high resolution with my watermark and wanted to resize them later for online purposes but thought that then my watrermark was too small. So I did the resize in the export as well and as the resize option is above the watermark option, to me it would only be logical to get a relatively larger watermark to my picture. Instead, the watermark was exactly the same size watermark relative to my original picture...

I want to automate this so I don't want to add the watermark (manualy) after exporting my pictures and resizing my pictures before exporting is not an option in lightroom. 

How couild I achieve this? How could I make lightroom add the watermark after my pictures are resized so the watermark is in teh right proportion?

I found it... A watermark itself has properties as how it should be positioned and if it should be proportional to the picture. So A bit of a dumb question, but I cannot find a way to delete it... woops.
