Path Function - Filter Multiple Parent ID's based on date range

HI,

I've read numerous posts and can't seem to find anything that solves this, so thought I'd ask.

I've an employee table, holding line mgr information and changes to this line mgt /  employee data over time.
The current record is marked by an IsCurrent Column

What I need to do:
When the path function comes across two records, it looks at the records that is current.

Or if I apply a date filte to my visual, I return the line management at that point in time.

So prior to End of July I have one Hierarchy and after this I get a different one for the employees shown below.

Is this possible?

TIA
