Clearbooks upgrade

I've just upgraded to the paid version because we have a few properties. I've been using the free version for several months and my account is a joint business account with my husband. In the olden days I just did our books and the accountant did his thing at the end of the year and told us how much tax to pay. With this new MTD on line way I believe I will need to split the rental between myself and my husband within the programme. Going forward how can I sort it so that from the beginning of this tax year (we don't need to submit until next year), I can itemise each of our properties and split the rental between us two. What is the process please?
