Now in time variables urls

Hi all,
I have a problem with adding __timefilters to an url in my table. Using the `{__from}and ${__to} works perfectly fine, but by using this variables, the now goes away and i get a timestamp of a certain moment, while i acutally want the time of the current dashboard so if this includes now I want now instead of an exact time.I also did not get the__all_variables` working.

Can someone help me to include now times int urls by the use of variables? ( i am using grafana 7.2.1)
