System interconnect diagramming software tools

Hi Raymarine Team,
Are there any Raymarine software tools you could make available to users to develop and document their individual systems diagrams? Most helpful would probably be a component library of all major Raymarine instruments & devices with their identified connectors, maybe even fitting cables - plug and play type. Would be great when planning upgrades to your systems, reduce returns, etc, and i am pretty sure there is a beta version in the shop somewhere :) As a semi techie, I truly would enjoy this feature.

If it can't be done, any recommendations what shrink-wrap product to best use for this purpose?

Thanks in advance!
Heiri
