Different symbols for Homematic IP climate devices

Hello,

I’m currently configuring my HomeAssistant using lovelace and mostly Homematic IP products. For Homematic I used the HACS Integration.
What I noticed is that there are different symbols of my climate devices.

HmIP-eTRV
HMIP-eTRV_01

My HMIP-WTH devices doesn’t show the heating or idle symbol which I find usefull.

Is it somehow possible to configure the HMIP-WTH to also show heating and idle operation mode/symbol?
