Unfortunately this facility is not available, as you will appreciate that each first holder is treated separately and hence we need to treat you and your spouse folios separately.
Since the folios in your name as first holder and your spouse name as first holder will have different PANs (of yours and your spouse), you cannot map the folios under a single User Id.
You and your spouse need to have separate User Ids. One User Id for your folios and one User Id for your spouse folios.
If you have folios in the name of your children and you are the guardian, you can map such folios as your PAN as guardian will be the same.
To further clarify, folios in the name of your children with your spouse as the guardian, your spouse can map such folios under User Id created by the spouse.
