Automate variable weekly wage payments to a payee from Barclays banking app

I have a job that pays me weekly on Friday. I am a strong believer in giving every £/$ a job and I want to make sure that every last £ from this goes towards my savings. I would like to automate the weekly transfer from employer A to Payee A (my savings account). Currently I have to (1) Log into the Barclays mobile banking app (2) Look at the amount paid that week (varies due to tips and hours) from the employer A (3) Select make a payment (4) Make a payment for that full amount to a payee in my Barclays banking app which is a 3rd party savings account. This system works until I decide I want to buy some new shoes, pizza or clothes etc. I would like an automated system within an android Barclays UK banking app that totally automates this task and allows me to save more often.
