P: Ability to Watermark images shared online

Here is a feature request that would help out so much in my workflow. I am continually sharing collection albums with clients via Lightroom syncing. The issue is that clients love to take screenshots of my work without paying for it. So, I have to export my photos with a watermark and then re-import them into Lightroom to sync with the cloud before sharing the album with them. Or, I may also manually create the album in my Lightroom gallery online and upload to it my exported images with watermark. What would be so helpful is the ability to add watermark to the virtual copies that get created and synced with Lightroom so I could share the album of watermarked images with my clients all in one step.

Pretty please!!
