Could you please provide support for more apps other than MFP in the calories in/out feature?

I would like Garmin to add support for multiple apps used for calorie tracking. I personally use HealthifyMe, and would at least like to have support for that. HealthifyMe does have support to connect to Garmin for step counting, but it’s not great. 
In the current version, Garmin just supports MFP which really limits the user to use the calories in/out feature.

Thanks,
