There is no similar functionality within the M365 admin center, or any of the workload-specific ones, at least not for "regular" customers. Only Partners/CSPs that have "delegate relationships" established with their customer tenants can use the multi-tenant switcher, as detailed here: https://learn.microsoft.com/en-us/microsoft-365/admin/multi-tenant/manage?view=o365-worldwide
For your scenario, you can consider using third-party tools that offer "portal replacement" type of solutions, or build something yourself, based on the Graph API/PowerShell.
