Samsung Volume set with Alexa

Configuration
1

Hello
I am new to HA and try to setup HA to controll my Samsung TV via Alexa i’m using HAASKA for the voice commands and everything works fine so far.
The tv is setup with the hacs component samsungtvsmart.

With alexa i can control power, channel, mute, etc.
But with the volume control I have a slightly problem: I can say: alexa set volume to X and the volume level of the TV is set to value X, but when i say alexa: tv louder - it jumps 10 units up or down. For example from 5 to 15 or from 20 to 10. thats a large step in loudness.
I seems for Alexa commands somewhere a fixed value to increase/decrease the volume?
The question is can i modfiy this behaviour? in best i want to increase the volume only in 1 unit steps

does anyone has an solution ?

Old topic but it seems it is still not possible (at least with the default samsungtv integration) to determine the step increase/decrease which i would love to have.

Cheers
