OS: Rename contact filter

On the contact filtering panel there is a filter "Date of the LAST process" - http://i.prntscr.com/JEt4L8GmSnuvh6knpb-OA.png But this filter does not filter by the Client's Last Process. For example, I specify the date from March 1 to March 31, but contacts that have processes in March get here, but there are processes later - for April / March / June / July, i.e. it filters contacts that just have a process in the specified interval, but this process is not necessarily the last one can it be renamed simply to "Date of the process", since the concept of "Last" has nothing to do with it?
