Hi gurus, 

In Madrid plug-in 'Change Management - Change Schedule' offers fantastic features on the Change Schedule report - screenshot illustrated as below, which has seemed fulfilling the core functions for my organisation like Zoom-in, condition builder (the funnel), frozen heading and many more.  I've been exploring this plug-in and wondering for some minor desired features like PDF/Export export, default to current date, and be able to collapse at different levels, is it possible

  • Is it possible to customise this report a lit more (given the fact the OOTB application Change Management – Change Schedule) 
  • How easy it is to do so?  If not, I was thinking of a plan B to involve Service Portal Widget development, but before this theory went too far, any advice would be highly appreciated.

 

Here is the list of the desired functions related to this report.

a lot of customers want to be able to do some more configuration on this 

it is especially anoying you cannot ad fields other than "number", "Configuration Item" and "Duration" 

hopefully this would be possible in next versions. 

there is the "time line page", but thats not to god either
