How do I edit MPC connectivity in Hyperworks 2022.3?

I've jumped in with both feet as far as transitioning from the classic Hypermesh UI to the new Hyperworks. For the most part, I've been able to find equivalent tools to run the usual operations that I'm responsible for, but this one has me stumped.

When I import a new mesh for a specific component to my model, I have to update the connectivity for a handful of MPCs. The MPCs each have about 3,000 independent nodes that need to be replaced with nodes on the new mesh. Because there's almost never the exact same number of nodes as before, the DOF weights also need to be updated after updating connectivity. I cannot find the tool to make these changes to an existing MPC in the new Hyperworks UI.

Opening the MPCs ribbon tool only allows me to create new MPCs, not edit existing ones.

The Hyperworks help page for MPC equations doesn't seem to have accurate information on this.
https://help.altair.com/hwdesktop/hwx/topics/pre_processing/model_build_and_assembly/mpc_create_edit_review_c.htm#concept_n1r_3ys_mmb

The page says that MPCs can be edited by double clicking an MPC, or by right clicking and selecting "edit". This should allow me to modify connectivity and DOF. However, doing this produces a menu with very limited options for editing the load collector, with no option to edit connectivity or DOF weights.

What am I missing here? How do I modify an MPC in Hyperworks?

    Hello,

    I am able to see this when double clicking on mpc

    The micro dialogue allows me to edit the dofs and weighting factors.
