How to edit Data Flow Task based on a dynamic connection manager more efficiently

I've created a dynamic OLE connection manager and it works fine now.  And I've also created a DFT based on this connection manger.

So far , it works fine. However, the problem is when I was trying to modify the OLE DB source inside the DFT. 

Because the connectionString property is populated by a variable during run time, I have to literally remove the expression on the connection manger and hard coded the connection manger in order to edit OLE DB source which is a sql query. It involves quite a few clicks ...

I am wondering if someone here knows a better way to deal with it?

Thanks
