Select desired month instead of current one

Hello,
I would like to insert 3 minicals in a page of a local rowing team, but only to show events in july, august and september. But minical always shows the current month.
Is it possible to add a parameter to the shortcode to show the desired month instead of the current one?
Something like this:
[spiffy-minical month=jul yr=2023]
[spiffy-minical month=aug yr=2023]
[spiffy-minical month=sep yr=2023]
Regards.
