Sending GA dimension without including a pageview

问题

From what I understand, setting a dimension:

ga('set', 'dimension1', 'value');

requires sending the dimension afterwards using:

ga('send', 'pageview');

My problem is that the header file with all my ga codes (including send pageview) loads before the file where I have my dimension. So if I send it again, won't I get two pageviews registered? Is there a way to do an empty send with ga and just send whatever has been set before it, nothing more?
