Anchor Plate Thickness for HIT-HY 200 V3 HIT-Z Application

Hi,

I'm trying to design a baseplate for a tube which will be connected to an existing foundation.
I'm using HIT-HY200 V3 HIT-Z but I'm getting the following warning "Acceptable fixture thickness with the given embedment depth is not covered by the standard product portfolio of the selected anchor (standard portfolio covers values between 0 in and 0.35 in). Please contact Hilti to discuss the feasibility of supply!"
I was wondering if I can use 1/2" or 3/4" thick plate, req'd embedment length is about 6".

Thank you.
