Multi POS mobile phone linked to the same online store location

I’m a new Shopify POS user that I just set up on my mobile. I have 2 concerns:

  1. Is it possible to link several mobile phones (example 10, 15, 50 associates) to the same location (of an online store) each with a different mobile phone under the SHOPIFY POS PRO subscription

  2. Is it possible to replace when launching the “SHOPIFY POS” application the LOGO of SHOPIFY and “SHOPIFY POS” by its own logo so that we do not know that it is this application? This is a bit annoying. Imagine that to start your online e-commerce store created under Shopify, it is first a big SHOPIFY logo that wanders on the screen and a term such as “SHOPIFY CMS” is displayed without your logo be visible. I want to see my LOGO (and not Shopify’s) displayed on the access code entry page on the mobile phone screen. Is it possible?

Thank you
