Handling equalisation and accumulation units from UK/IE funds

Most of my fund holdings are accumulation units, which have notional distributions (taxed as dividends) which is typically recorded as increasing the cost base (so that you’re not taxed a second time as capital gains). These distributions often also include an equalisation payment (a return of capital), which would correspondingly reduce the cost base.

How does anyone handle these in Sharesight? It seems to pull in the dividends but doesn’t have any awareness of the fact it’s an accumulation-based share class.
