Deleting Text and Dimension Styles without remapping

In the past I have been able to delete text styles and dimension styles and any text or dimensions on those styles would put on the <none> style.  This was good, especially since it helps us clean out files we get from architects and surveyors for our use and the deletion of those styles would leave the elements in their current state (text size, arrow size, etc), just not fixed to a style. We recently upgraded from SelectSeries 4 to the newest version of MicroStation CONNECT and now when we try to delete styles we are forced to remap the elements to a new style, this creates an issue as it changes all of the text height and justifications.  Is there anyway to get around this and have the elements shifted to <none> again to avoid this issue?
