Automatically adding Tireless Precision

I'm looking to add tireless precision to my Vedalken's Arcana checks, which is a permanent 1d4 to Arcana checks.

Although this thread has a solution: https://app.roll20.net/forum/post/8874284/additional-1d4-for-ability-checks-of-specific-races
The solution only applies if the character sheet is toggled to always roll with advantage. If not using that, when changing from normal to advantage the attributes and abilities settings for Arcana reset and do not save.

I've also looked at adding a Global Skill Modifier for 1d4 but that does not seem to work so any help would be fantastic!

Hi Jonathan, 

The solutions here that I am aware of are:
1) Make a macro for Arcana (or all skills actually) that includes your 1d4. 
2) Use a Query in a Global Skill Modifier. The query asks if it is an Arcana roll, and if yes, it rolls 1d4. If no it does not roll 1d4.
3) Head over to the Mods (API Scripts) forum and ask for help with a Mod (API script) that listens for an Arcana roll then rolls an additional 1d4 when Arcana is rolled. 

Thanks for the reply Gauss, the API suggestion is certainly great but what would the Query in a Glob

al Skill Modifier look like to ask if its an Arcana roll?

Put this where you normally put 1d4:
?{Is this Arcana?|Yes,1d4|No,0}
