As stated in https://bugs.documentfoundation.org/show_bug.cgi?id=96718
Working with a formula in Calc: Data => Validity is a very powerful option. (Especially a matrix-formula for a custom cell-range. Very good!)
But entering could be a pain.
A formula could be used in each condition (Whole number, Decimal, ...), but the used cell ranges must be typed!
Using names and "Insert => Names => Insert" does not help, because LibreOffice does not allow this function while "Data => Validity" dialog is open.
(In Excel it is possible.)
Make available "Insert => Names => Insert" in Validity
Thanks for the issue. Set to new!
Bug is still present. No changes in bug behavior.
