How to insert User Shape for concrete in Connect Edition

Hi there,

I'm currently using Prostructures CONNECT edition Update 1 V.

I've created a User shape and want to use to place concrete then add rebar.

In previous version of Proconcrete the user shape option would show up when placing concrete slab (etc).

I can't find this option in any of the concrete placement options.

Where can I find or has this been replaced with another method?
