Planning to apply for U1 but missing payslips

I'm planning to leave the UK and want to apply for U1 and U2. I've paid NI contributions throughout the last several years. However, I'm missing payslips for end of financial year for a couple of years. I have downloaded PAYE details and confirmation of my NI contributions for those months from the HMRC Government Gateway site. Can I use this to replace the missing payslips when I submit by U1 application?

Hi

We ask that you send any payslips that you have, however if you don’t have them all available you can still apply just sending what you do have, you can also send any P60’s you have

Thanks
