According to the KB article about Filtering Timesheets (http://support.manictime.com/knowledgebase/articles/686265-filter-timesheet) RegEx is supported, but when I tried to combine two separate tags into the filter (like "or"), it didn't work as expected.

For example: I want to include in the same timesheet, entries from two separate tag groups. For instance, "Client, Project 1" and "Overhead, Task 1"

If I only wanted to show the "Client, Project 1", I can do this filter:
//
"Project 1"
//
let's say 5 entries are returned.

if I do:
//
"Task 1"
//
let's say 2 entries are returned.

If I want to have all 7 entries returned together, obviously this doesn't work:
//
"Project 1"
"Task 1"
//
(returns 0 entries because there are no entries which use a combination of those two separate tags)

Thinking to use RegEx as the KB article suggests, I tried this:
//
"Project 1" | "Task 1"
//
but that returns everything tagged with ANY tag - not what I want at all.

Is there some way to indicate that tag A OR tag B should be present for the entry to be returned?
