Yes, didn't find one

Is your feature request related to a problem? Please describe.

This request addresses a limitation of the current Home Assistant MQTT discovery support.

The scenario: A device with more than one independent LED strips, configured via SetOption68 1 as described in https://tasmota.github.io/docs/#/Lights?id=independent-pwm-channels

The result:

UI and control works as expected, however,

"homeassistant/light/B6DB61_LI_1/config":
{"name":"Küche Bar-LEDs","stat_t":"B6DB61/tele/STATE","avty_t":"B6DB61/tele/LWT","pl_avail":"Online","pl_not_avail":"Offline","cmd_t":"B6DB61/cmnd/POWER1","val_tpl":"{{value_json.POWER1}}","pl_off":"OFF","pl_on":"ON","uniq_id":"B6DB61_LI_1","dev":{"ids":["B6DB61"]}}

"homeassistant/light/B6DB61_LI_2/config":
{"name":"Küche Unterschrank-LEDs","stat_t":"B6DB61/tele/STATE","avty_t":"B6DB61/tele/LWT","pl_avail":"Online","pl_not_avail":"Offline","cmd_t":"B6DB61/cmnd/POWER2","val_tpl":"{{value_json.POWER2}}","pl_off":"OFF","pl_on":"ON","uniq_id":"B6DB61_LI_2","dev":{"ids":["B6DB61"]},"bri_cmd_t":"B6DB61/cmnd/Dimmer","bri_stat_t":"B6DB61/tele/STATE","bri_scl":100,"on_cmd_type":"brightness","bri_val_tpl":"{{value_json.Dimmer}}","clr_temp_cmd_t":"B6DB61/cmnd/CT","clr_temp_stat_t":"B6DB61/tele/STATE","clr_temp_val_tpl":"{{value_json.CT}}"}

discovery messages are still sent as if the device was configured with SetOption68 0
