Make the project node handle in a more handy way the udim maps to get visualized in the canvas view-port, more efficiently.
justification
the tile treatment, i think it could be easier. instead of having to add as many nodes as the tiles are, the udim project( and maybe a udim/Multi-mat bake node) could use to compact a series of maps of the same name with different tile number in one input.
Implementation
it should have a toggle in the project node itself instead of using the external per-process node, in a way to make the process way more intuitive and fast, especially in case of high tiles number.
so it should looks more like this in that case:
