Lead Calling Time Category

Hello there

I am new here, so in case this topic already exists, I am sorry, maybe you could send me the link.

The case is that my leads are international, some have to be called at certain moments of the day. For example, some have to be called during my very early morning, others late in the afternoon and some whenever during the day.
Is there any possibility to categorize or filter my leads in this way?
I don't want to schedule each single lead and it doesn't have to be precise in terms of country or area code.
Thank you!
