Macro for Alternating Magic Weapon Bonuses?

In a campaign I am in I just recently got two weapons (+2 and +1) and am wondering how to make a macro specifically to alternate attacks with them? I currently have a macro but it only allows flat modification not variable, so I am wondering how I would create a macro for the current ones? I need it to be able to do multi-attack too since I am doing a lot of attacks. I have separate ones for attack and damage rolls as well.  They are both rapiers and current rolls would be +9 to hit, 1d8+7 dmg +8 to hit, 1d8+6 dmg I am fine if those numbers are hard baked into the macro as I can just adjust them later as needed. 

What game are you playing? (There are over 300 different game systems on Roll20.) Which character sheet is being used for the game? If you're not sure, please post a screenshot. (There are over 1,000 character sheets on Roll20, and many games have more than one option. For example, D&D 5th Edition has over 10 character sheets that can be used.) It's very likely that there are other solutions besides a macro that will do what you want, but those will rely on which Roll Templates are available, which are based on the character sheet selected for the game. 

It is not letting me reply for some reason, but I am using a separate character sheet so that is why I need/have been using macros. 

I saw your reply in my notifications but it is not showing up on the page for some reason. Like I said in the initial post it is a +2 rapier and +1 rapier. 

Bumping this because I still need the macro(s). Is there a way to indicate advantage in macros as well? 

Again:  1. What game are you playing? 2. Which character sheet is selected for the game?  The answer to those two questions will greatly determine the answer you get. If you can’t answer those two questions, you’re h likely to have anyone be able to adequately help you. 

Also, if what you want is a setup where you click a single button and the first time your character attacks with the +2 rapier and the next time you click it your character attacks with the +1 rapier, I think scripts may be required. They would certainly make things easier. Are you in a game owned by a Pro/Elite subscriber?
