Shuriken Texture Sheet Animation How to choose Random Row Between 2 Constants?

I want to choose a random row within a range, not to choose one of all rows. I dont know why there is no arrow on the right to randomize the current row between 2 constants.

.

Have the developers forgot this or this not possible? I doubt it, because when there is a random toggle, the value gets randomized between 0 and rows length-1, so they could overwrite the min max as parameters where you pass custom borders just like every 'random Between 2 Constants' option.

.

In my opinion, The random row toggle is restrictive and should be removed. Instead, the row int should get the arrow options, so you can set a specific row, or a range of rows or all rows.
