Prog{x} Time select list

[RhysMcW]

Hi
I finally got around to installing the addon, great work on this, and updated most of my NodeRed flows to use the new sensor names, all working great so far except one bit, the Prog{x} Time select lists...
The Prog{x} Time select lists populate with the time in 15 minute increments. The Sunsynk system mode settings adjust the time in 5 minute increments and I have various functions that adjust some of the times based on things like sunrise and sunset, and adjust by the 5 minute interval.
This was not a problem for me when I was using NodeRed and it's modbus to update the inverter daily but had to disable the NodeRed modbus to enable this addon. With the Prog{x} Time select lists only having 15 minutes intervals I'm not able to change the value to something not in the select list.

Would it be possible to get the Prog{x} Time select lists to populate in 5 minute increments, instead of the 15 minute interval it currently done?
I understand this would create a longer list to select from, maybe then parameter driven from the config so users can select their own interval...
