Definitely! You can add as many credit and debit cards, banks, and sub-accounts with the same bank as you wish. The only limitation is linking accounts held under different login credentials at the same bank, which Hurdlr doesn't currently support.
Tap More (•••) > Banks and Integrations > Add Income Account/Add Expense Account > enter your online bank login credentials -> tap Continue > toggle on each account you'd like to sync for your income/expenses > Save. Repeat the account selection process for both income and expense accounts as desired.
