Linked sheet with new columns + manual edits

Question

I have a sheet with rows prepended by an app (call this primary sheet). I want to create a secondary sheet that will auto update when the primary sheet is updated. I also want the secondary sheet to have additional columns in which specific cells are updated manually.

For example: Primary Sheet

Header1 Header2
row21   row22
row11   row12

Secondary Sheet

Header1  Header2  Status  Updates
row21    row22    New     blah1
row11    row12    Done    blah2

...where "Status" and "Updates" columns are updated manually.

I have tried using =IMPORTRANGE("https://docs.google.com/spreadsheets/d/xxx","PrimarySheet!A:B") and =query(PrimarySheet!A:B, "select * where B contains 'blah' ") but I can't seem to get the Status and Updates field to move down with Header1 & Header2. For example:

Secondary Sheet

Header1  Header2  Status  Updates
row41    row42    New     blah1
row31    row32    Done    blah2
row21    row22    
row11    row12  

I'm hoping the Secondary Sheet should be:

Header1  Header2  Status  Updates
row41    row42    
row31    row32    
row21    row22    New     blah1
row11    row12    Done    blah2

Any suggestion on how to get the desired outcome?
