Auto-fill fields with variable id and name (regex?)

Using KeePass with KeePassRPC extension, Firefox browser.

There is a site of a bank: https://inteligo.pl/secure that autofill does not work for login, as field with login is different each time you refresh the page (id as well as name). The field is for example:
<input name=“client_id_field_0287260152-client” value="" id=“f-form_0287260152-client_id_field”

where the number is different each time you refresh the page. Is it possible to force Kee to fill this field somehow, like using regex for name /client_id_field_.*-client/ and same for id or something similar?

I prefer to avoid Auto-Type, as I would like to have it filled in instantly as I open the page, same as on other pages.
