Banking book & Trading book

Dear SBT Teams,

According to the instructions in the FINT v2 version, “The coverage requirements for equity- and fixed-income investments apply to all securities in the banking book while securities in the trading book are optional”. I have the following two questions to ask:

Could FVOCI (Fair Value through Other Comprehensive Income), FVPL (Fair Value through Profit and Loss), AC (Amortized Cost) these three Account cover both banking book and trading book?

If we want to present banking book and trading book separately, could we add rows in the submission form in order to calculate Portfolio Target Boundary?
