As in, do you always have to click once per placement, or is it possible to click and drag to place assets along the grid?

Since I will need to place hundreds of floor tiles, having to click for every one would actually be more tedious in the long run than doing the select+duplicate method. Duplicating and moving a 10x10 grid of tiles is less work than manually placing 100 new tiles, after all. If I could paint them on though, then the asset placer would still be preferable.
