How do you automatically sequence leg altitudes on IFR approaches?

Hey There:

Hardware: 2 10” HDX, Garmin GPS 175, Garmin SL30, 2 axis Dynon Autopilot

Is there a way to get the 175 to send to the Dynon Autopilot the DO NOT GO BELOW altitude of the next waypoint when on an IFR approach? I can enter the altitudes manually and tell the autopilot the altitude I want it to descend to and the VS at which I want it to descend at, but is there a way to automate that information between the 175 and the Dynon autopilot?

Also the HDX displays the VS Req’ to destination, which i use all the time. It is an awesome feature. Is there a way for it to tell me the VS Req’ to the next Waypoint on the flight plan, specifically those that are part of the IFR approach plate?

Thanks in advance. Pic of setup attached.

The GPS175 doesn't have enroute VNAV. Only once established on an approach can you engage VNAV and fly the path. For initial phases of approach, enroute transition, before VNAV is available, I'll just set next altitude in the alerter to protect myself and use VS or IAS to descend. Level off, set next altitude, keep going. At some point you can arm VNAV and catch the glidepath down.
