Can’t change wordpress / woocommerce atribute value order

I’m making a website/webstore in wordpress/woocommerce and ran into a problem with product atributes and swatches. We sell engraving materials (layered sheets) with a lot of different colors. So I put color as one of the atributes and in the atribute I inputed values. There are about 70 different colors and the problem is I cannot order the colors so that they form a “rainbow order” because wordpress or woocommerce doesn’t allow more than 20 atribute values per page when editing values and the order in which they are shown on site. It also doesn’t allow to drag and drop a atribute value from one value page to another.

I have tried different orderings. But it would really need to be custom. I could input each color in desired order, however if later I need to input another color, I can’t order it correctly.

In the picture is just an example. If I try to move greens order up (or down) on same page (page 2 of values) I can do that no problem, but I need to put it on page 1 of atribute values.
