A320 OE Taxi Flow

[MD83FO]

Hello all,
I’ve been noticing that many airlines are applying the one engine taxi as a flow instead of a read and do, as this is no longer a supplementary procedure but rather, normal operation.
how can I go about implementing this change? Airbus is not very helpful on the tech request.

At my airline, we perform this supplementary procedure by memory, but this is derogatory to the rule which remains for everything else.
We did not add it to the normal procedures either.
