Point 99 in Modality and expressions with be is defined as:

a limited range of expressions with ‘be’ + infinitive (‘be allowed to’, ‘be supposed to’, ‘be able to’) with present and past forms of ‘be’ and with modal ‘will’

‘Supposed’ overlaps in B2 also.

There is also some overlap with 106 in Modality ‘Plan’.

*This is where the English Grammar Profile makes it hard to use.  When you read the description: ‘be able to’ with modal ‘will’ from above you think that is all you need.  But actually  ‘will be able to’ is also found at A2:

When we check for this code on iweb _vb supposed|able|allowed to _vv we realise that ‘able’ drowns the rest out.

*’Able’ and ‘were’ is A2 by default too in the EVP.
