Display the dates of two date columns from different tables in one measure column

[ubg]

I have two tables.

Is it possible to write a measure that displays all dates in one column?

See example.

Many thanks for your support

Table A  

Table B

Desired result in measure

Have you considered appending these tables instead?

Thank you very much. The suggestion has enabled an interim solution, which I have also implemented.
However, this extends table A and makes its structure more complicated.
But wouldn't it be possible to solve my problem using variables?

You cannot create calculated columns or tables from measures.
