NEC4 PSC Option E Programme changes

Hello, I accepted a quote from our PSC to undertake design work under Option E (cost reimbursable). The programme submitted at the time reflected the activities in quote provided. Since the acceptance of the quote, the scope has been reduced, and this had been captured for recording purposes in a CE. I have not accepted the first programme yet. My question is, since I haven’t accepted the first programme yet, should the first programme be the programme submitted alongside the quote, or can I request that a revised programme is submitted and used which reflects the scope change? I understand if this was Option C I would need to accept the programme alongside the quote as the first programme, but given this is Option E, is this slightly different?

Thanks in advance!
