Create measure from original source, regardless of slicer choices

I have a source table that is filtered by a time slicer.

What I what to know is whether it's possible to create a measure that uses data from that source table, but not filtered by the slicer (i.e. to be like the original source). So, I need some of the measures to use the filtered source, and some of them not to depend on the slicer selection.

 Thanks in advance
