Slider with Checksum

Is it possible to use the slider with a hex command that requires a
checksum at the end of it?

This will be for direct volume on a TV.

Examples:
\x08\x22\x01\x00\x00\x00\x2B - Volume to 0
\x08\x22\x01\x00\x00\x10\xC5 - Volume to 10
\x08\x22\x01\x00\x00\x64\x71 - Volume to 100

The sixth byte would be replaced with [sliderval].
Since that number will change to where ever the slider is moved to, it
is going need a different checksum for each different volume level.
The checksum is two's complement and is the seventh byte as shown.
Will this be possible?
