How to create model by profile (AECOsim)

Hello people~

I need an advice about modeling way.

I wanna make a retaining wall in 'Building Designer task'. Not a 'Microstation' task. Especially 'Architectural Design-Place Wall' tool.

For example, 

1st - Make a profile in 'Parametric Cell Studio'.

2nd - Put in the custom properties(information) into the profile.

3rd - Import to AECOsim and place wall.

I have to make a library with custom properties.

But, don't know how to make.

Please advise me.
