Very easily it can be done in load case editor by making new load case for anchor load.

In piping stress analysis and support specifications, such core issues need to be fixed at basic design stage. If anchor is used only for thermal load, not for any seismic or accident load like steam generated water hammer, some gap at axial stop can reduce thermal load.

But, issue of design of anchor is not the responsibility of civil only, piping stress owns the design when they sign the anchor design. After all, piping stress and supports design is a team effort of civil and piping!
