Allow for more than one gotowebinar account to integrate with Hubspot

Why hasn’t anything been done about this in 2 years? We have been sold an enterprise account that we thought could be used for different brands; however, using more than one webinar account is intergral to our use. This is very frustrating! I was hoping there was at least one webinar product that would allow this with HubSpot, but I was told there is not. HELP!!
