SaaS user Purchase Phone Number

I have been testing the SaaS option in Chat Dash as I love the idea of it. Is it possible for a SaaS user to purchase a phone number via the interface, or is it limited to importing only via SIP currently? AND if it is limited, is it on the roadmap to add this feature. I fear it will be very limiting and confusing for an average user to have to purchase a phone number elsewhere, then import it. I think they would sooner use another service that has it all combined. Thank you.
