How can I set my form to be available at a certain date and most importantly, a start time?

We have classes that fill up extremely fast and are offered at a first come, first serve.  We really need a start time feature so people don't try to sign up before registration opens.

Thanks!

We currently do not have an auto enabling option for the forms.

I will forward this as a feature request to our developers, I can t give you an expected date of delivery but based on the number of user requests regarding this , the feature might be given priority
