Is it possible in Colourspace to manually input a patches value?

For example, colourspace displays a 255 Red Patch and then the recorded value is manually inputed, without a probe?

Yes - use the Virtual Probe to 'add' virtual measurement.
Then double click the point in the CIE graphs, and manually edit it.

Thanks Steve, sorry I should have been more clear - is there a way to enter an RGB value rather than X,Y value?

Sorry - I have no idea what you mean?
RGB values are the patch triplet values, not measured values.

Is there a way to create a LUT/Profile from a series of patch values that are manually entered, with RGB numbers, bypassing the probe.

I just want to make a LUT to align two different cameras. I could put the recorded patches on a screen and probe them but it'd be a long winded way of doing it.

Sounds like you need MatchLight.

And how would I go about getting that? - no links exist

It's all on the website: https://www.lightillusion.com/colourspace.html
Select the LUT Extraction, ICC, VCGT option from the drop down.
