vba turn every possible trendline in a pivotchart blue

[cogswel__cogs]

Hi,

Could someone help me with code to turn every possible series trendline blue in a pivotchart. I have an automated process that builds charts and for some reason with missing series sometimes trend line changes color. I only have one trendline but I think k its when the series changes due to a missing series that it changes color. So i just wanted to write something to change them all to blue knowing there will only be one.
Any help is greatly appreciated.
