Phrase pump - Spanish accent

Language Reactor has completely changed the way I learn Spanish. The phrase pump is especially useful for ear training. However, most of the accents are from Latin America - and my only opportunity to use Spanish is in Spain. I get that it is useful to be exposed to all accents, but there really is no need for me to struggle to understand one of the accents (which only seems to consist of vowels) when I am only ever going to be able to use Castilian. Ideally, I would like to choose what accent the Phrase pump uses, but I would be pleased if there could be an increased % of the phrases in a Castilian accent. Many thanks for a superb learning tool!
