MURs are being axed at the end of the 20/21 year, so probably no more after March 31st 2021. May be more useful to look into being up to date on CPCS and courses recommended to be competent to provide that and also NMS too.
CPPE lists several learning resources (A to M) on their self-assesment document to provide the service. e.g. Consultation skills course.
Maybe you can persuade your manager these would be more useful in the future and he/she can get someone else to finish off the MURs. I think you can only do 100 now, not 400.
UPDATE!!

2020-2021
The total number of MURs which you can complete in 2020-21 is 100 MURs. The service ends at the end of 20-21 financial year.
Changes to Target Groups from 1st October:
Remember -You need to update your SOP
New targeting requirements apply to Medicines Use Reviews (MURs) conducted from 1st October 2019, so community pharmacy contractors will need to update their standard operating procedure for the service to reflect these changes.
Seventy percent of MURs conducted from 1st October 2019 to 31st March 2020 must be within the following two target groups:
patients taking high-risk medicines
or
patients recently discharged from hospital who had changes made to their medicines while they were in hospital
From 1st October 2019, patients with respiratory disease and patients at risk of or diagnosed with cardiovascular disease and regularly being prescribed at least four medicines are no longer target groups for MURs.
