Can you use the HasOneValue function in a measure?

When you first load the page, the function will return false, so you can return BLANK or 0 or a message about selecting something using the slicer.

Then when the user has made a selection, the function will return true and you can return the result they are looking for.

This may not work if users can select multiple values for a single column.
