How can I use a longer than 80mm anchor for supporting a URM arch. PROFIS only allows a maximum of 80mm. Is there a way to check more than two anchors in a single row?

We are trying to support from the top a brick arch. We will install a steel beam (PFC on the flat) and drill from the top through the arch and install chemical anchors at 600mm spacing. We plan to drill 700-1000mm deep.
