You can go ahead with this on June 15th and even the June subscription if it is ready.
Hi The Minis Maniac,
I've moved these items to your sidecart, so they should get combined with your June order.
We cannot suspend your June order until the 15th, as it has not been generated yet. So, we can either:
A) Suspend your subscriptions, then you can contact us when you are ready for them to be suspended and have the order generated
or)
B) Once your June order is generated (and you have the order number for it) - just let us know to suspend it until the 15th. You can just respond to the order confirmation email if you want.
Let us know what works better.
Thanks!
