Inserting multiple 16x16 tiles in a 8x8 map

Hi,

I am currently using a 16x16 tileset on a 8x8 map. When selecting a range of tiles and inserting them, they are placed in adjacent 8x8 cells and therefore are overlapping each other, leading to a distorted image.
It would be better and mor intuitive if tiled inserted them at each second cell only, so that they are not overlapping each other.

Greetings,

No file, test, or entry point is named. Reproduce multi-tile insertion with a 16x16 tileset and 8x8 map, then trace the tile-selection and placement workflow; done means selected tiles are placed on every second map cell without overlap.
