Whilst building up a new drawing, I imported many Xar's, and every time it asked "Match Colours" in this instance, I didn't want too, but since it asked me every time, I said don't ask me again ....... Stupid move!!!

Now in another drawing, I am again importing many xar's but DO want to match colours. I have now got a single drawing with multiple identical colours in the bar.

How do I get it to ask "Match Colours?" again ....

Thanks.
