Search Feature for SharePoint Attachment Menu

We use the new SharePoint attachment feature more than any other kind of attachments now. It's great that it lets us link directly to the SharePoint file, so that the attachment in wrike stays up to date with the latest version in SharePoint. However our SharePoint document library is massive, and finding the right document sometimes takes a minute or two of clicking through folders and scrolling.

It would be great if this File Attachment menu had a search feature to search through the selected SharePoint site for the folder or document you need.
