Higher of two dice, N times?

Due to an interaction of two rules, I ended up in a situation where I could use a macro to calculate the value of... "The highest of (dice roll A, dice roll B, fixed value), rolled N times". I was wondering if there's a way to make this in a way that doesn't spam up the entire chatbox, but I am... not well experienced with rolls. The ideal version would be a popup that asks the values of A, B and N, and then calculates the fixed value based on A and B, but it's not vital.

Unfortunately roll20's macro system doesnt support the "rolled N times" part - you need to be a Pro Susbcriber and use a custom script to do that kind of thing. For the "highest of" part you can use a group roll and the kh1 (keep highest one) operator, like {1d6, 1d10, 7+0d0}kh1 When using this you cant group rolls with non-rolls, so that last is a fixed number - 7, with +0d0, to trick roll20 into thinking that is a dice roll. Alternativelly you could do {[[1d6]], [[1d10]], 7}kh1 inline roll brackets [[ ]] convert a dice roll into a number, so here there are three fixed rolls.

Hm! Not perfect but can always be used without TOO much spam, if even with a simple /r. Or something fancier to hide all the rolling if I can figure it out.

If you wrap it in inline roll brackets [[ ]], it will just show the result, no need to use /roll at the start, like /me rolls a total of [[ {1d6, 1d10, 7+0d0}kh1]] (That demonstrates how you can embed inline rolls in other lines, and dont need the /roll command.)
