Drainage and Utilities Adjust a Utility Profile

I'm using Drainage and Utilities (ORD 2021) to model existing utilities with elevation.

I have data of existing utilities with elevations above ground and under ground.

I used the "Extract From Graphic" to get the first profile with offset from surface and than planned to edit the profile according to this video but it didn't work as well, I'm having difficulty to adjust the elevation along the lines. The "Break Element" command allows only local change, but for my work I need "clean board".

Another way I found is to use the "Table Editor" and than I can edit each and every point - adjust the station and the elevation.

As I think it might be easier to complex geometry the lines and set the profile as I need- but then I won't be able to use the abilities of the Drainage and Utilities application.

 Is there a quick way to set the profile elevation as I need?

Thank you,
