Can you set the starting place for a pattern on an image in PS 7?

Is there any way, that when you apply a pattern to images, that it can be applied from the bottom left corner outwards ? It’s for a watermark that is meant to start at the bottom left and be repeated every 4cms.

Each image of a few 100 is sized differently.

Any help appreciated.

What about creating another image of the same size, filling it with the pattern, flipping vertically so the pattern starts in bottom left instead of top left then copy/pasting it into your main image.

Thanks Dan, it’s appreciated, but the watermark is a word, so if I’ve understood you correctly, it would be upside down. Sorry, I perhaps should have mentioned that the watermark was a word ;-(

Any help much appreciated.
