Custom pony wall alignment ???

[xtal_01]

Hello,

 

I have a two part question ...

 

1) how can I ... or can I ... have a custom alignment of my main wall above my pony wall?  I have a 2 x 6 wall on top of 4" blocks.  I see under alignment "outer surface, main layer outside, wall center, main layer inside, inner surface" ... but I want a specific distance.  In my case, 7/8" from the outer face of the 2 x 6 stud / sill ... or 1" from the inside of the stud / sill to the inside face of the block  (both the same as the "real" block measurement is 3 5/8").

 

2) is there a way of adding a layer between the upper and lower wall?  I want a custom sill 7/16" wider (5 15/16 pressure treated sill) than the sill that is part of the wall (the wall will be built then stood up and attached to this).

 

Thanks .... Mike
