Ligthroom custom resize function won't allow for unsual format

Hello,

I was wondering if you all got the same problem regarding resizing.

Basically I would like to crop to a medium format size, especially 6x4.5. However the dialog box won't let me set 4,500 - even though there is until three decimals, Lightroom will snap to the closest preset crop format, say, 6x4 or 6x5.

So I usually find myself putting 6x4.51 or something similar, which I think is a very stupid bypass for an issue that shouldn't be existing in the first place.

Any feedbacks from the team or from users about this issue ? Are some other people experimenting the same thing as well ?

Thanks !
