TSVB - Top N - Item URL: keep time interval when link to other dashboard

I´m using the "item url" in TSVB visualization to link to another dashboard.
In the new dashboard the search is already filled with the value of "{{key}}"
(thats ok).

When link to another dashboard I also want to keep the selected time interval. Is this possible?
Maybe I have to set &_g=(time:)?

This is my current item url with a static time interval of one hour :

Can somebody help me?

You should use the dashboard drilldown feature for this, because otherwise you won't be able to persist the time range. This feature was introduced in 7.8
