Yes, this is possible but not recommended.
Please refer to this thread for detailed explanation: Crafting using a one button macro
Each comma denotes the next step in the crafting rotation. So in order to use two ingame macros, you would have to skip the number of steps in your first macro.
Let’s assume that your Macro #1 has 10 steps.
A corresponding Miqobot entry would look like this:
1,,,,,,,,,,2,
Please note that we do not recommend using this method.
If a lag spike occurs, your ingame macro will be messed up and most likely the crafting will get stuck. Miqobot macros are different by design, because they are bound to each crafting step precisely. Miqobot macros are more lag-proof than ingame macros.
But of course, please choose whatever method suits you best.
