Certainly can, refer page 163 of the scheme booklet:
Converting from a direct holding of Pensana UK Shares to a Pensana UK CDI holding If holders of Pensana UK Shares wish to convert their holdings to Pensana UK CDIs, they can do so by contacting Computershare. Computershare will not charge a fee to a shareholder seeking to convert Pensana UK Shares to CDIs (although a fee will be payable by market participants). In this instance, underlying Pensana UK Shares will be transferred to CDN and a holding statement for the CDIs will be issued to the relevant security holder. No trading in Pensana UK CDIs on the ASX can take place until this conversion process is complete.
