add phone /address section

dears, is there (simple) way, how to add another “Customer support” section? Called let say “Invoicing support” with phone + email to Accountant departement?

and to add additional info? Reg-ID, VAT-ID, Bank Account…..?

And to add there “row of text”, for example
“The company is registred…… ”

And to change word “Phone” I′ve to directly modify template, right?

Thanks, Zdeněk
