Sprite Sheet Selector Node - for bomber input

I wish that there was an easy way to load a bunch of different images to be used as a bomber - like a big sheet array. Thinking like a big 8x8 grid of items, which could be then chosen via mapped input, and return the one to be used for the bomber component.

Imagine:
You have a big grid of possible bombers (ie a 'sprite sheet'), loaded as an image. It is the input for the 'Sprite Selector' node. The output is the same as 'bomber adapter'.
Other inputs define the number of rows and columns, and X and Y select, which could be driven either by a integer input or a map input.

(I know that you can make something similar using scripting, or just elaborate lookup confections. It would just be nice to have an out-of-the-box-official node.)

Yep, that's what I want it to do, but as a node.
