I wish to add residential addresses in the Peak District of Derbyshire - a "typical" rural area of the UK. Currently, it is impossible to do so within the WME as a residential place if that address contains anything other than numerical data [aside from a limited suffix].

Here is a sample of the data I would like to add; from just one postcode of one small village - maybe 25 to 30% of the total addresses in the village:
Ashford Cottage, Chapel Street, Monyash, Bakewell, DE45 1JJ
Ashford House, Chapel Street, Monyash, Bakewell, DE45 1JJ
Avonlea, Chapel Street, Monyash, Bakewell, DE45 1JJ

Of those 49 addresses - all of them residential - only 5 include a numerical element, of which 4 relate to a terrace of cottages built perpendicular to the street the address relates to [i.e. their "entry point" is at the same place on the street] - and one of those four has a house name as a part of the address too!!! [we British like to name our houses, it appears to make where we live look "posh"].

This is by no means atypical of the situation in most of rural Britain.

We *NEED* to be able to add [and edit] RRPs with alphabetical characters in WME ASAP otherwise whole swathes of Britain will remain unmappable with regard to their addresses. This is especially important because although it is possible to approximate a nominal position on a street full of house numbers, from a couple of known fixed points, it is impossible to do so on a street full of house names [or a collection of random alphabetical characters as it would appear to an alogrithm].

Edit: I was going to add this as a new idea, but I saw Kevin had got here before me - over 2 years ago! It is scarcely credible that this idea has not been progressed since that time.

This is very similar to the need we have in in the US where some areas have house numbers that start with a cardinal letter (i.e. N,W, E,W). These are un-editable in WME if created by a user in the app.
