Lightroom CC Custom Watermarks

Now that the mobile app has the ability to add basic watermarks, I think there should definitely be a way to add a custom watermark like Lightroom Classic offers. The Lightroom CC app is far more streamlined and runs smoother on my devices, so having the ability to add my custom watermark to my photos would save me tons of time and hassle
*side note, I would even be happy if Lightroom Desktop (cloud based) recieved this addition over the mobile app
