I would love it if Zotero was able to cite Archival material correctly using MHRA as follows:-

11.2.9 Manuscripts
Names of repositories and collections should be given in full in the
first instance and an abbreviated form should be used for subsequent
references. The degree of abbreviation which may be acceptable will
depend upon the frequency with which a particular repository, collection,
or manuscript is referred to and upon any possible ambiguities. The
names of manuscript collections should be given in roman type without
quotation marks and the citation of manuscripts within collections
should be according to the system of classification of the repository.
The following examples show a suggested method of citation for first
references and possible models for later references. Note that, because of
the danger of ambiguity, the abbreviations ‘fol.’ and ‘fols’ are preferred
to ‘f.’ and ‘ff.’. The abbreviated and superscript forms for ‘recto’ and
‘verso’ are also preferred.
