UK: Automated computation of UK CGT on stock trades?

Does anyone know of a good automated solution for calculating **UK** capital gains tax on stock trades? I've been looking but haven't found anything reliable that correctly applies the UK rules (same-day matching, 30-day matching, and the Section 104 pool). Curious if others have found a tool that handles this properly.
