Set a table column as web URL does not take effect when connect to SSAS

I missed the screen copys when posted the message. Here I update the full message as below. Sorry for any confusing.

I want to have a table column as web url to redirect to a webpage, when I connect to Excel table, it works fine. But when I connect to SSAS via direct query. I can not select a measure field as target URL, and I can only select FormatString of measures. But I can not set FormatString as my target URL. As below screen shows:

Similar issue happens with button text, if I select a measure as button text, and the border color of field selection dropdown becomes red, as below screen copy shows. While ######.FormatString could be selected.

Can anyone have solution to solve the problem? Or Power BI team can remove this constrain?

Best regards,
