Yep, you can do this:

Can Idle Master be used to pad my playtime of a particular game?
The steam-idle.exe application that's included with Idle Master can be given a command line argument of the appid of the game you'd like to idle. For example, if you'd like to idle Team Fortress 2 for playtime, you can simply run "steam-idle.exe 440" from a command prompt. There is no user interface for this, it must be done through the command line.

Where would i put the command? i have no knowledge of this kinda stuff

First way
Make shortcut for steam-idle.exe and after .exe add gameid
For example, it looks on my pc like this (for CS:GO):
C:\Mukoki\Steam\IdleMaster\steam-idle.exe 730

Second way:
Windows button + R -> cmd (command line) -> C:\Mukoki\Steam\IdleMaster\steam-idle.exe 730
And its same
